setup.py was building most perf sources causing setup.py to mimic the Makefile logic as well as flex/bison code to be stubbed out, due to complexity building. By using libraries fewer functions are stubbed out, the build is faster and the Makefile logic is reused which should simplify updating. The libraries are passed through LDFLAGS to avoid complexity in python. Force the -fPIC flag for libbpf.a to ensure it is suitable for linking into the perf python module.
